all function allows the post-fader surround
and stereo monitor output channels to be
simultaneously muted. The channel mute/
solo section provides post-fader surround
and stereo channel monitoring control,
allowing a single channel to be muted or
monitored. Multiple channels can also
be simultaneously selected for muting or
“soloing.”
A special solo mode is also provided,
called channel pop solo, which offers a
unique aid in monitoring audio material.
Channel pop solo allows the level of a sin-
gle post-fader monitor output channel to be
raised while the level of the other channels
is reduced. This helps to emphasize the
content on one channel without fully mut-
ing the others. Broadcast applications can
benefit from the channel pop solo mode
by allowing, for example, the center chan-
nel to be highlighted while still maintain-
ing some level on the other channels. The
amount of level increase—the “pop”—as
well as the amount of attenuation can be
configured to meet the needs of specific
applications or users.
Two functions allow the input sources to be
checked for level or phase inconsistencies.
The 5.1 to stereo downmix function is used
to create a stereo signal from the selected
surround (5.1) source. The stereo to mono
downmix function allows audio on the left
and right channels to be added (summed)
and monitored on the center output chan-
nel. The two downmix functions can be
simultaneously enabled, allowing a sur-
round source to be checked for mono com-
patibility. The downmix functions always
impact the post-fader surround and stereo
digital and analog monitor outputs. A con-
figuration setting allows the pre-fader sur-
round digital monitor output to be selected
for pre- or post-downmix operation.
For flexibility, the StudioComm for Surround
system is designed to easily integrate with
equipment such as production intercom
systems, on-air or recording tally signals,
and audio consoles. Two remote-control
inputs provide access to the mute all and
dim functions. By providing access to these
functions, talkback or slate activity from
an audio console or other communications
system can control the level of the post-
fader surround and stereo digital and
analog monitor outputs.
Installation
In this section you will be installing the
Model 76DA Central Controller in an equip-
ment rack. Connections to the digital audio
inputs and digital and analog monitor out-
puts will be made. A dedicated digital audio
timing reference signal can be connected
to the sync input. If desired, external equip-
ment will be interfaced to the remote control
inputs. A location will be selected for the first
Model 77 Control Console and it will be con-
nected to the Model 76DA. AC mains power
will be connected to the Model 76DA. For
advanced applications up to three additional
Model 77 or Model 71 Control Console units
can be connected to the Model 76DA.
System Components
The main shipping carton contains one
each of the following: Model 76DA Central
Controller, Model 77 Control Console,
9-pin D-sub interconnecting cable, and user
guide. Also included in the shipping carton
is a North American-standard AC mains
cord. Your dealer or distributor should
provide an AC mains cord appropriate for
destinations outside of North America. Any
additional Model 77 or Model 71 Control
Consoles will be shipped in separate
cartons.
